3 Layer Co-extrusion Production Line

1. Multi-layer co-extrusion cast and film lamination

This unit can realize plasticization, quantitative extrusion and cast molding of plastics through three independent small single-screw extruders, and realize multi-layer co-extrusion cast molding and multi-layer film extrusion, so as to prepare multi-layer co-extruded composite films of different structures and functions;

2. Casting performance testing of film materials

Testing the extrusion and cast performance of film materials by adjusting the plastic formulation and process conditions for the formulation development of film materials;

3. Film extrusion cast molding and film compounding process optimization and quality control

Through small single-screw three-layer co-extrusion cast laminating unit, the optimal extrusion and cast process parameters of film materials of certain materials and structures can be prepared, which can be used to guide the setting and adjustment of the actual production process and control the quality of films.

 

1. Multi-layer composite structure: The film produced by the 3 layer co-extrusion production line for plastics casting and blown film has a three-layer composite structure, which can ensure the abrasion resistance, mechanical strength and anti-oxidation performance of the film.

2. Gravity direction extension: The 3 layer co-extrusion production line for plastics casting and blown film makes films by gravity direction extension, which can make the films of uniform thickness and can exclude particles, bubbles and other impurities from the formation process.

3. Required plasticization precision: The 3 layer co-extrusion production line for plastics casting and blown film can plasticize the film precisely. This precision is important for applications where film material performance is required, such as medical, food and electronics.

1. Packaging materials: The three-layer co-extruded cast and blown film production line can produce transparent, soft and breathable films, and this excellent performance makes it widely used in various packaging materials such as food, pharmaceuticals and medical supplies.

2. Agricultural film: Agricultural film has always been an important field for rubber film production. The three-layer co-extruded cast and blown film production line can produce high-strength, durable, impermeable agricultural film and plastic covering materials.

3. Industrial materials: rubber films are also widely used in industrial fields. The 3 layer co-extrusion production line for plastics casting and blown film can produce films with different physical properties, such as oil-resistant, high-temperature-resistant and insulating films, by controlling different ratios of raw materials, viscosity and other factors. These films can be applied in industrial fields such as machinery, electronics and automobiles.
